IMPRQvEMnNT' IN GAR-SPRINGS.

The ScheduleV referred to in these' Letters Patent and making part of the same specication, inwhichf AFigure `l is a perspective view ofa carspring em.-

bodying my invention.4 4I'n this figure the top of the casein which the materialferming the spring is `con'- tained is removed. U

lignre 2 is a perspective view of the top part of said case turned upside down.

Figure 3-is'a sectional view of..` my spring, cut

l throughkon the dotted li'ne'x, in fig. 1.

Figure 4'i's a .sectional iiew of the same spring, cut through ondotted line y, in fig. 1. Figure `5' is a sectional viewof the same spring, with another 'form of the case, which lmay be used,;if preferred., l

My invention 'consists in combining, for the purposesv of a carsprin'g, one orlmore Icolumns of rubber,v

in a"'suitable case, with feltedwool, -oi other equivalent -librbus material, packed into'and substantially fillingth'e v.cas'efwand external tofand around the rubber columns, for' the purpose of supporting the rubber, and in agmeas'ure preventing its outward lateral spread when under pressure.. i

A is the case, made ot.cast'irou, or any other ,suitable material, designed to receiveand hold the rubber and wool. This case should be made in two parts, A"A", the upper part, A, forming a top or cover, havinga deep rim or iiange, @that sits down over the' lower part or body A of the ease.

It' preferred, the top Ainay bemade to lit into and move within the. body A-,`being extended up above the'topof 4the rubber and wool, as shown in tig. 5.

B indicates a number of columns ot' rubber, ard ranged within the case A.

' 4. C indicates an'umber of layers of woolfelt, cut to fit the size and shape of the case, and enough of them are used to fill theV body olf thelcase nearly or quite to the height of the columns of rubber. Circular pei'- forations are made in Athese layers of felt, corresponding in size and position with the columns of rubber as arranged Ain the case, through which the rubber may pass. The wool is thus made to iill the caseand surround the columns of rubber.

The top and bottom` partsof the case are held toge'th'er by bolts c c', which are passed up through the recessed columns d d in the lower jpart, and through the holes e e' in the top part, and secured by the nuts f f',-that are received in the 'recesses gg' in the top face of the upper part. These bolts thus hold the two parts of the case together, while the top part is allowed to move in or'upon thc lower, with the `motion ot' the springs contained in the case.

Wool in a felned.l state, as described, I consider 'the most serviceable. in the case without beingfelted.

Claim..

What I- claim as my invention, and desire to secure and combined substantially 'as and for the purposes' specified.
